Unable to build opencv for android using cmake

edit

I managed to build OpenCV 2.4.9 for java following the online instructions.

However I am unable to build for Android

I am using OSX Yosemite, CMake 3.0.2, OpenCV 2.4.9.

The output I get is the following:

======

I tried setting both: export ANDROID_NDK=~/android-ndk-r8e and export ANDROID_STANDALONE_TOOLCHAIN=~/android-toolchain

but both give same error. Any clues to what is causing this? Bad version of CMake?
